Hello, it's October 9th, 2026, you're listening to Linux Kernel Daily.
Today's signal is late-cycle networking stabilization: a big fix pull for 7 point 3 release candidate 7 that trades new work for defensive checks around packet buffers, checksums, and driver ownership.
First, scale. The merge tagged A F 32 D A 4 pulls 128 networking fixes covering Bluetooth, wireless, WireGuard, CAN, and Ethernet. The pattern is regressions from recent releases: a Bluetooth deadlock, a CAN metadata regression, bonding breakage in I A V F, packet forwarding slowdown in Mana, and removal of buggy V…
Second, don't touch a buffer you don't own. Two commits to the M A C B driver, 6 B 48 E D 8 and 9 1 5 1 D 6 C, fix a reboot seen from a Raspberry Pi C M 5 generating cloned packets. The driver was appending its frame check and padding to shared buffers in place and modifying buffers before checking transmit space,…
Third, small state bugs with outsized impact. In WireGuard, commit D 0305 F 8 closes a handshake race where a duplicate response processed on two threads could resurrect an old session, and commit 6 5 A B 9 D E preserves the timestamp label when encapsulating, fixing log spam and pacing…
